Occuption: Dry stock sheep and beef farmer
Implementing change to reduce risk posed by internal parasites to parasite control.
Michael has been farming in Gladstone for 13 years, having transitioned from a career in the rural service industry, including roles with Williams and Kettle, PGG Wrightson, Elders, and Ballance Agri-Nutrients. His tenure as a farmer began when his wife’s parents were looking to retire, a succession plan was worked out and Michael and his wife have been running the farm ever since.
Michael is a shareholder and supplier for Atkins Ranch, a farmer-led brand supplying premium produce to the likes of Whole Foods in the U.S. His farm runs a self-replacing Romney flock, breeding both replacements and terminal stock. With 4,000 breeding ewes and 1,500 ewe hogget replacements, the goal is to finish all lambs through the Atkins Ranch Group.
Committed to high-levels of animal welfare and premium farming, his operation is GAP (Global Animal Partnership) certified, ensuring year-round, pasture-raised, grass-fed livestock. Since 2019, the farm has also been part of the Land to Market program, aligning with regenerative agriculture principles.
Michael focused on a proactive and strategic approach to dealing with parasite resistance, seeing it as an inevitable challenge that must be delayed and managed effectively. His focus is on minimising drench use, selecting actives wisely, and incorporating strict quarantine protocols for incoming stock. Testing plays a key role in his decision-making, allowing him to drench only when necessary, rather than following blanketdrenching practices
“Obviously it’s pretty widely publicised that drench resistance is here and I’m talking more probably triple resistance than anything. It’s always on the forefront of our mind, it feels like it’s sort of going to be the inevitable in time. So if we can try and delay it somehow or prolong it, that’s really first and foremost on our mind. Zolvix Plus is probably one of our main tools to prolong a healthy drench resistance status.”
Zolvix Plus is a critical tool in his program, used both as a quarantine drench to ensure new stock arrives clean and as an exit drench before winter to reset the farm’s parasite status. By integrating good pasture management, alternating grazing species, and ongoing monitoring, he has built a system that prioritises a long-term sustainable operation and profitability.
